Cl. 49-449 7Claims ABSTRACT OF THE DISCLOSURE Window-frame structure with an outerframe composed of two C-shaped sheet-metal sections and two inner frameseach composed of two U-shaped sheet-metal sections, each inner frameaccommodating a respective glass pane which is slidably held therein andcan be independently locked to the lower part of a respective outerframesection; the inner frame sections can be detached from the outer framefor installation and removal of the panes.

The present invention relates to a window-frame structure adapted to beinstalled in a wall opening of a dwelling house, preferably in anopening provided in advance in a prefabricated wall of a building.

According to the invention the frame of this window comprises an outerframe element constituted by a section formed from a folded sheet-metalstrip and at least one inner frame element likewise constituted by afolded sheetmetal section which receives a glass pane and is fixed byits periphery to the said outer frame element.

Thus, with the aid of a single inner frame element and one pane it ispossible to obtain a window with fixed pane; but it is equally possible,with the aid of two coupled inner frame elements fixed to the same outerframe element to obtain an opening window with the aid of two panes eachof which occupies only part of one of these inner frame elements and iscapable of sliding in the latter.

The section of the outer frame element preferably comprises a flange forfixing it to the building and a flange for supporting the inner frameelements.

In a preferred embodiment of the invention the window is of rectangularshape and has rounded corners, so that the sections of the outer as wellas the inner frame elements may be continuous and bent at right anglesin the corners of the window. Moreover, in order to avoid any necessityfor welding or mounting the sections, the outer as well as the innerframe may consist of two parts merely joined end to end, the jointsbeing situated on the different sides of the window as regards the outerframe and the inner frame or frames.

In order to make possible the easy replacement of a pane in the case ofbreakage, the joints of the inner frames are situated in a horizontalplane so that the frame sections are in two parts, one corresponding tothe upper and the other to the lower part of the pane.

Thus it will be suflicient to dismantle only the upper portion of aninner frame in order to insert a pane in the lower portion and then tohold this pane in place during the re-assembly of the said upper portionof the inner frame.

The following description, given with reference to the accompanyingdrawing and by way of a non-limiting example, will help to understandhow the invention may be put into practical effect. In the drawing:

FIGURE 1 is a view, in elevation, of a window according to oneembodiment of the invention;

FIGURE 2 is a sectional view on the line ]1II of FIGURE 1;

FIGURE 3 is a sectional view on the line III-III of FIGURE 1;

FIGURE 4 is a sectional view on the line IVIV of FIGURE 1; and

FIGURE 5 is a view taken in the direction of the arrow V in FIGURE 4.

As shown in the accompanying drawing a window comprises an outer frame 1formed by two C-shaped halves 1D and 1G, connected end to end twovertical junctions 2.

As shown more particularly in FIGURE 3, the sections of the outer frameare composed of a strip of suitably folded sheet metal so as to comprisetwo peripheral flanges, i.e. an outer flange 1a and an inner flange 1b,the flanges being integrally connected by a fiat portion 10. There-entrant angle between the outer flange 1a and the flat portion 10enables the frame to be supported on an inner bounding surface 3a of anopening provided in the wall 3 of a structure, for example a facingwall.

The outer face of the portion 10 as shown is shaped to form a gutter 1dwhich is for collecting condensation from the window panes and alsoserves to reinforce the connection with the opening of the building byimproving the quality of the joint in this region.

The two frame sections 1D and 1G of the outer frame may be fixed to thewall 3 by screws inserted through apertures 5 in the flange 1d.Condensation in the gutter 1a is adapted to drain a hole 25 and througha duct 26.

The inner peripheral flange 1b is bent back on itself to provide areinforcement and inner frames 7 and 8 are secured thereto by screws 6.Each of the inner frames comprises an upper, invertedly U-shaped half 78and 88 respectively and a lower, U-shaped half 7 and 8 respectively,formed of sheet metal folded into Y-section, the two inner framesections meeting at two horizontal junctions 27 offset from junctions 2.Sections 7 8 form peripheral ribs 7, 8 juxtaposed on one side of flange1b and traversed by the fastening means 6.

In the longitudinal groove formed by each Y-section there assembled aU-shaped lining 9 in which rests the edge of a respective glass pane 10and 11.

The linings 9 ensure a tight joint between each pane and its frame andalso facilitate the sliding of these pan s in the frames. For thispurpose these may advantageously consist of a super-polyamide such asthat known com mercially as Nylon.

The panes 10 and 11 each extend a little beyond half of the lateralwidth of the window opening so that they overlap at the vertical middleZone of the opening. In order to ensure weather tightness at theoverlap, the vertical inner edge of each pane is provided with a sealingstrip 12 of rubber-like material, each strip being disposed along anedge of the pane and having a lip 12a which, by virtue of itsresilience, is pressed against the other pane. Each sealing strip isheld in place by a U-section clip 13.

Each U-section clip 13 fits around a metal plate 14 (FIG. 2) which issecured to the pane by a single bolt 15. The metal plate has anoutwardly extending arm having a handle 16, at its free end foreffecting the horizontal displacement of the panes.

When in closed position the panes are adapted to be independentlyimmobilized by respective locks shown in FIGS. 4 and 5.

As shown, each lock is supported by an arm 18 fixed to the lower part ofa respective section 1D, 1G (FIG. 1) of the outer frame 1. The lockcomprises a tubular holder 19 in which there is mounted a detent pin 20having a knob 21 secured to one end, the other end 20a of this pin beingadapted to pass through a hole in the corresponding pane.

The pin 20 has a lug 22 engaging an axial groove 23 in the tubularelement 19, the groove terminating on the side adjacent the pane in asegmental recess 24 which constitutes a bayonet lock for the catch 22.

Normally, one or both panes may be opened as required, the pane on theright (FIG. 1) is displaced to the left after the release of thecorresponding lock.

The pane 11 on the left (FIG. 1) is displaced toward the right, afterthe release of its lock, so that the two panes may be cleaned from theOutside by reaching out with ones arms through the free spaces on thesides of the inner window frames.

In order to insert or replace the panes, their lower edges are assembledin the lower frame sections 7 ,8 and are then shifted sideways andlocked by the locking pins 20. Afterwards all that has to be done is tocap the upper edges of the panes with the upper halves 78, 85 of theirframe sections and to fix the latter by means of suitable screws.

The panes are preferably a few millimetres thick and are hardened, inorder to make them more resistant to impact.

For windows with a fixed pane only one frame 7 or 8 is used, which wouldoccupy the whole area of the frame 1.

Obviosuly, modifications may be made to the embodiments described here,especially by the substitution of equivalent technical means, withoutthereby departing from the scope of the present invention as defined inthe appended claims.
